Cops witness shooting, chase down gunman on West Side

A 21-year-old man also fatally shot in Edgewater Beach

Chicago police chased down and arrested a gunman who shot and critically wounded another man on the city's West Side, authorities said.

The shooting was one of at least four late night shootings occurring across the city.

Officers saw the unidentified man open fire on the 33-year-old victim at about 10:20 p.m. in the 4300 block of West Madison Street in the West Garfield Park neighborhood, police said, citing early reports.

The victim, who was struck multiple times in the back and abdomen, was taken to Mount Sinai Hospital in critical condition, police said.

The officers quickly chased after the gunman finally taking him into custody. Police hadn't determined the motive for the shooting, saying that suspect wasn't cooperating with investigators.

Earlier in the evening, a 21-year-old man was shot in the chest as he exited a building in the 5600 block of North Winthrop in the Edgewater Beach neighborhood at about 9:30 p.m., police said.

Two men fled the scene on foot, police said.

A person with the victim put him in a vehicle and drove several blocks to the 6100 block of North Broadway, where they flagged down a passing squad car, authorities said.

The victim, David O. White, of the 5100 block of North Winthrop Avenue, was taken to St. Francis Hospital in Evanston, where he was pronounced dead at 1 a.m., according to the Cook County medical examiner's office.

No arrests had been made in the slaying, police said.

About a half-hour later, a 23-year-old man suffered a non-serious graze wound to the abdomen in the 5700 block of South Indiana Avenue, police said. He was taken to the University of Chicago Medical Center for treatment.

Just before 11 p.m., a woman was shot in the arm in the 4700 block of West Washington Boulevard, police said.

The victim, who was in her late 40s or early 50s, was taken to Mount Sinai for treatment, police said.
